Preach. I have little time for someone once this is understood about them. 90% of people

Many times over the years I had to ask the person I was in convo with "are you actually listening to me or are you just waiting to talk?" I find it quite irritating.

I used to do this! I would be listening to what a person had to say and already forming a reply in my head! When they would question whether I was listening I would get offended!

It took a long time for me to understand that you listen by hearing the words, feeling the atmosphere, seeing their body language, and not thinking about a reply until they had said all they needed to say!
